We are pleased to be able to fioure a white-flowered form of the charming 
Odontoglossum veaillarivm. Within the last few years there have been added to our 
collections several new and attractive varieties—some with brightly coloured blossoms, 
others with large rose-coloured lips—all producing fine showy flowers; and, besides 
these, there are many other variations to be found amongst the abundant importations. 
They are free-growing plants and profuse bloomers, and with their numerous graceful 
eee of flowers overhanging the light green foliage they make useful plants for the 
exhibition table as well as for home decorative purposes. The O. vexillarium albwn, 
Which we now illustrate, will produce a fine effect amongst the high coloured forms. 
We received the materials for our sketch from the well-grown collection of Mons. A. 
H. Finet, of Argenteuil, France, in which it has flowered for two or three meceger? 
years. It was exhibited at Paris in 1884, when it was awarded a first prize, and, 
certainly, it well deserved that honour. We have subsequently received from R. H. 
Measures, Esq., of Streatham, a few flowers of the white variety called 0. — 
“rum Measuresianum, which is essentially different from the one we now figure; this 
latter received a First-class Certificate from the Royal Horticultural Society 1885. 
Odontoglossum vexillarium album is a free-flowering and distinct variety. It 
Produces white flowers, which have but the faintest tinge of rose colour towards the
